Standard physics textbooks generally deal with an idealized parallel-plate capacitor, where the size of the plates is much larger than the separation between the plates, something that is not true in the situation shown in the simulation. Which of the following are true for the standard textbook situation (let's call that a capacitor with infinite plates) but are not true in this simulation? Select all that apply.

1.) In a capacitor with infinite plates the electric field in all three regions (above the top plate, between the plates, and below the bottom plate) points in the same direction.

2.) In a capacitor with infinite plates there is no electric field in the regions above the top plate and below the bottom plate.

3.) In a capacitor with infinite plates changing the voltage across the capacitor while keeping the separation between the plates constant results in no change in the electric field between the plates.

4.) In a capacitor with infinite plates changing the separation between the plates while keeping the voltage across the capacitor constant results in no change in the electric field between the plates.

5.) In a capacitor with infinite plates the electric field is maximum along the plane parallel to, and halfway between, the plates.

6.) In a capacitor with infinite plates the electric field in the region between the plates is uniform.

7.) In a capacitor with infinite plates, doubling both the capacitor voltage and the plate separation results in no change in the electric field between the plates.
